    摘 要:目的 研究温度对小儿胃动力的影响. 方法 健康儿童40例，随机分为温水组及冷水组，每组20例，温水组平均年龄为8.8岁，冷水组10.5岁，两组摄入水的温度分别为37～40℃和4～6℃，每例饮水300mL，在B超下观察两组不同时间点的胃运动及排空情况. 结果 60min时胃体蠕动频率以温水组(2.8±0.7)次·min-1 快于冷水组(1.5±0.5)次·min-1 ，但冷水组90%及100%胃腔排空时间明显短于温水组，分别为(19.1±3.1与31.9±7.1)和(52.5±3.7与59.5±3.0)min.两组10%，50%，90%及100%胃窦排空时间分别为(0.8±0.8与2.8±0.3)，(4.5±3.8与17.4±0.4)，(17.2±2.2与41.7±1.8)和(49.2±3.8与56.4±3.6)min，冷水组均明显短于温水组，胃腔与胃窦残留率与上述结果完全相符. 结论 冷饮可使胃排空加速，频繁饮用低温饮料可能干扰胃的正常运动节律.
